"Grandpa, is it because she's not used to living in my home that she keeps not coming back?"
"Grandma, I'm not going to keep talking with you right now. I have to hurry home, otherwise my mom and dad will start to worry. My mom and dad love me so much, I can't let them worry about me. They should live happily, they shouldn't have to live every day on edge because of their son. If that happened, my heart would be ill at ease!"
"You really are a sensible child. I believe your mom and dad must feel that having you as a son is their greatest pride. You're the person they care about most in their hearts, aren't you? Little friend, you still haven't told me your name, and what your mom and dad are called."
